Quadriceps-hamstrings intermuscular coherence during single-leg squatting 3–12 years following a youth sport-related knee injury

The purpose of this study was to determine the degree of co-contraction as per electromyographic gamma-band intermuscular coherence of the quadricep (Q) and hamstring (H) muscles during single-leg squatting (SLS), and to assess the influence of sex and self-reported knee complaints on the association between knee injury history and medial and lateral Q-H intermuscular coherence.Participants included 34 individuals who suffered a youth sport-related intra-articular knee injury 3–12 years previously, and 37 individuals with no knee injury history. Surface electromyographic signals were recorded from medial and lateral thigh muscles bilaterally to determine the gamma-band (30–60 Hz) intermuscular coherence between medial and lateral Q-H muscle pairs during SLS. Multivariable linear regression (α = 0.05) was performed to investigate the relationship between knee injury history (main exposure) and medial and lateral Q-H coherence (outcome) while accounting for the influence of sex and self-reported knee pain and symptoms (covariates).The median age of participants was 25 (range 18–30) and 67% were female. Q-H gamma-band coherence was present for 60–90% of legs. Medial and lateral Q-H coherence was higher in females compared to males. There was no evidence for an association between medial Q-H coherence, knee injury history, knee pain, or symptoms. There was evidence for an association between knee injury history and lateral Q-H coherence, which was modified by sex such that previously injured males demonstrated reduced Q-H coherence compared to uninjured males.These finding suggest that females demonstrate a more pronounced Q-H co-contraction strategy during a SLS than males regardless of knee injury history. Further, that male who suffered a youth sport-related knee injury 3–12 years previously demonstrate less Q-H co-contraction during a SLS than uninjured males. The mechanisms behind differences in neuromuscular control between males and females as well as previously injured and uninjured males require further investigation.     

The effect of decision timing on the willingness to costly reward cooperation and punish noncooperation: Sanctioning the past,the present,or the future

Numerous studies have demonstrated that sanctions can promote cooperation. However, it is important to know not only that sanctions can work but also under what conditions people are actually willing to sanction cooperation positively (i.e., reward) or noncooperation negatively (i.e., punish). In this article, we demonstrate that people use sanctions less often and sanction more mildly when they decide about sanctioning before (instead of after) the occurrence of others' (non)cooperation (Experiments 1 and 2), regardless of whether they decide directly afterwards or after a time delay (Experiment 2). Moreover, we reveal that beforehand (as compared with afterwards) people have not yet formed clear sanctioning preferences (Experiment 3). These findings corroborate our reasoning that the decision environment beforehand induces nonconsequential reasoning and thereby hampers people's willingness to sanction. We discuss the theoretical, methodological, and practical implications of our work.     

The generalizability of reactions to assessment: An application of the Selection Procedural Justice Scale (SPJS) in academic settings

This study tested the Selection Procedural Justice Scale (SPJS) in an educational setting. The sample consisted of 617 students. Four different confirmatory models were tested, followed by an IRT analysis to test the scale structure at the item level in the two different contexts (selection vs. academic exams). Results indicated that the 11‐factor structure is the best factorial solution, and SPJS items were found to be free of DIF.     

Le juge,le médecin et le détenu. Regard critique sur la suspension de peine pour raison médicale

The purpose of the article is to give a critical view of the “suspension médicale” (a kind of compassionate release), which is often considered as a “humanist” law. Based on a research conducted on the experience of prisoners at the end of their lives, it appeared that many more or less objective criteria are involved in the decision-making process. In this context, physicians and magistrates try to articulate their actions according to expertise. The decision of granting or refusal also depends on the perception of the prisoner's personality. The application of the law thus reflects the tensions and alliances between medicine and justice in the treatment of a deviant and vulnerable population.     

Quelle juridiction est compétente pour juger des faits commis par un professeur des universités-praticien hospitalier qui sont en rapport avec son activité d’enseignement ?

Constituted courts of ordinal authorities are not competent to judge facts committed by a university professor-hospital practitioner, which are related to his teaching activity. Only the court specific to hospital teachers, which is seized by the ministries of health and higher education, is competent to judge those facts.     

Religious education,a matter of understanding? reflections on the final report of the Commission on Religious Education

In this article we offer reflections on the final report of the Commission on Religious Education (CoRE) that was published in England in 2018. We expose and problematise the prominent place of understanding in the report, not only as an educational method, but also the underlying world view of the report itself, a world view which we characterise as ‘hermeneuticism’. We raise educational, theological and political concerns about the particular approach taken in the report. We propose instead that religious education (RE) should be considered first of all in terms of what it means to live with a religious or non-religious orientation, conceived in existential terms rather than in terms of beliefs or practices or objectified world views. Educationally we show that what we term a non-hermeneutic way of viewing our humanity would open different possibilities for RE and its future.     

Age-related changes in word retrieval vary by self-reported anxiety but not depression symptoms

Tip-of-the-tongue states (TOTs) are known to increase in frequency across adulthood, but there is wide variability in older adults’ TOT rates, suggesting that individual difference factors contribute to TOT incidence. We investigated the role of affect by examining the relationship between self-reported anxiety and depression symptoms and the frequency of TOTs during a laboratory task. Participants were young, middle-aged and older adults in a population-based sample of adults aged 18–87. Increased anxiety was associated with fewer TOTs for the middle-aged group but more TOTs for the older adult group. There was no relationship between anxiety and TOTs for younger adults and no relationships between depression symptoms and TOT incidence for any age group. We discuss our results in terms of attentional control theory, which provides an explanation of how age may affect the relationship between anxiety and TOTs.     

Feature selection using Ant Colony Optimization (ACO) and Road Sign Detection and Recognition (RSDR) system

Road Sign Detection and Recognition (RSDR) is aimed to enable drivers maintain basic functionality with the aim of identifying and notifying driver through the existing restrictions so that the process is a success on the present widened road. Examples for RSDR include ‘traffic light ahead’ or ‘pedestrian crossing’ signs. An innovative RSDR system has been introduced which comprises of pre-processing, edge detection, feature extraction, features selection and Ensemble Fuzzy Support Vector Machine (EFSVM) classifier. Feature selection is carried out successfully by deployment of Ant Colony Optimization (ACO) algorithm to determine most prominent and definitive features. These features are then fed into the ensemble SVM to enable both road side traffic detection as well as recognition. Suggested system’s performance is analyzed and evaluated with respect to road signs having a capable recognition rate.     

产品空间位置、价格音节长度对消费者价格感知的影响

本研究采用实验法考察了视听单通道及双通道下产品空间位置与价格音节长度对消费者价格感知的潜在影响。结果发现,呈现在空间右侧以及以较长音节播放的产品使得被试的价格感知升高;短音节条件下,个体对空间右侧产品的价格感知显著高于空间左侧,长音节条件下两侧则无显著差异;相对于单通道刺激呈现,视听通道呈现信息一致时出现信息冗余效应,个体判断的速度更快,验证了共激活模型假设,视听不一致条件下的速度降低则支持了预测编码模型。
